Abstract: A brake controller of a machine can be configured to determine brake power associated with braking operations, such as operations to slow the machine or maintain a speed of the machine. The brake controller can allocate the brake power among systems such as a battery system, a resistive grid, auxiliary systems, a mechanical brake system, and/or other systems, based on a defined priority order of the systems. For example, the brake controller can prioritize using a regenerative brake system to charge a battery system during a braking operation up to a currently-available capacity of the battery system, and allocating any remaining brake power to a lower-priority system. The mechanical brake system can be the lowest-priority system, such that use of the mechanical brake system can be avoided unless an amount of brake power exceeds capacities of higher-priority systems to consume the brake power.

Abstract: A throttle control system and method for use with a vehicle. The throttle control system receives an input voltage from a vehicle throttle controller. The throttle control system prepares a throttle signal and provides the throttle signal to the throttle to force deceleration to a selected speed or constrain acceleration to a selected value. Preparing the throttle signal may follow detection of maximum threshold values of speed or input voltage. The maximum threshold values may be specific to the location of the vehicle. The throttle signal and the maximum threshold values may be defined with reference to the input voltage, vehicle speed, vehicle location, or other parameters. The throttle signal may force deceleration or constrain acceleration incrementally to mitigate loss of vehicle throttle controller responsiveness to driver commands. The throttle signal may be an output voltage provided to a vehicle electronic control module.

Abstract: A brake control apparatus includes: a master cylinder that outputs a brake fluid at a master pressure; a master pressure changing device that can change the master pressure irrespective of an operation of a brake pedal; a brake actuator; and a control unit that executes antilock control by reducing a brake pressure of a target wheel. Modes of the antilock control include a normal mode and a pseudo mode. In the pseudo mode, the control unit operates the master pressure changing device such that the master pressure obtains a target value of the brake pressure of the target wheel, and changes the brake pressure of the target wheel in an interlocking manner with the master pressure. When the normal mode is unavailable, the control unit executes the antilock control in the pseudo mode.

Abstract: A vehicle speed management apparatus acquires scene information about a driving scene of a host vehicle, estimates the driving scene based on the scene information acquired, acquires behavior information about a driving behavior of a user, determines a driving risk of the host vehicle driven by the user, based on the driving scene estimated and on the behavior information acquired, and controls a presentation of assist information by an information presentation unit in order to prompt the user to address the driving risk. When the driving scene estimated represents an independent traveling state of the host vehicle, the assist information to be presented by the information presentation unit is selected based on a magnitude of the driving risk determined before an operation by an emergency control unit.

Abstract: A cruise control system for a vehicle includes a controller configured to maintain a speed of the vehicle about a setpoint, and in response to predicted brake capacity falling below a threshold based on predicted brake fade, reduce the setpoint and downshift a transmission of the vehicle to increase negative torque to reduce brake fade. Also, a powertrain of a vehicle includes an engine, an automatic transmission coupled with the engine, and a controller. The controller is configured to maintain a speed of the vehicle about a setpoint, and in response to a predicted brake capacity falling below a threshold based on predicted brake fade, reduce the setpoint and downshift the transmission to increase a negative torque.

Abstract: An estimated time-to-collision (TTC) calculation apparatus includes a distance acquisition unit, relative velocity acquisition unit, relative acceleration acquisition unit, and estimated TTC calculation unit. The distance acquisition unit acquires a distance X between the own vehicle and an object. The relative velocity acquisition unit acquires a relative velocity V of the object with respect to the own vehicle. The relative acceleration acquisition unit acquires a relative acceleration β of the object with respect to the own vehicle. The estimated TTC calculation unit calculates an estimated TTC t until the own vehicle collides with the object. In this apparatus and method, the estimated TTC calculation unit calculates t, based on the distance X and the relative velocity V, when the own vehicle is accelerating, and when the own vehicle is decelerating, calculates t based on the distance X, the relative velocity V, and the relative acceleration β.

Abstract: A system for determining the length of a road train includes controllers on both towing and towed vehicles. Each controller may transmit a vehicle length and GPS coordinates in a specified wireless message format. The towing vehicle controller receives a first wireless message from the towed vehicle controller. The wireless message includes at least one of a speed of the towed vehicle, a length of the towed vehicle and GPS coordinates of the towed vehicle. The towing vehicle controller determines if the towed vehicle transmitting the message is coupled to the towed vehicle and then adds the length of the towed vehicle to the length of the towing vehicle to attain an overall length of the road train in response to the determination that the towed vehicle transmitting the wireless message is coupled to the towing vehicle. The towing vehicle controller then transmits the overall length of the road train.
